Cool chill game I enjoyed it. I don't know if there was a goal ?
I get that in a jam, it can be hard to find the time to make a tutorial, but I wish I could've reread the intro text while playing, I ended up on a cuple occasions opening a new window of your game just to reread that as I forgot it said while playing. Also took me some time to find out that r-click allowed me to rotate parts and I couldnt figure out what the upgrade button was for.
But overall cool game.
